4 Colors

If you know Uno, you already know 4 Colors — match the card in play by color or number, dump your hand first, and watch out for the special cards that skip players or force draws. It plays with up to three opponents, and a match can run long since the win condition is reaching 250 points across multiple hands rather than winning a single round outright. The randomness in the draw keeps any two games from playing out the same way.
